The RX1 has something like a short zoom lens built into it. Because the 'clear view zoom' function on the camera renders images of 35mm, 50mm and 70mm of excellent quality but reduced file size. This function is essentially different from digital zoom because it crops rather than up-scales the files. Those who complain about the RX-1 limiting them to 35mm haven't read the owners manual carefully enough. Or they are hyper critical of the quality rendered by the 50mm and 70mm settings.

The problem is that Clear view zoom forces you to shoot in JPEG only. I prefer to shoot in raw and do my own cropping.
